The following code specifies the behaviour of strict DER checking. Note that this function tests a signature byte vector which includes the 1-byte sighash flag that Bitcoin adds, even though that flag falls outside of the DER specification, and is unaffected by this proposal. The function is also not called for cases where the length of sig is 0, in order to provide a simple, short and efficiently-verifiable encoding for deliberately invalid signatures.
